Wireless Charging RAPT Pill Hydrometer & Thermometer (Pre-Assembled, Red Housing)

This pill hydrometer already has been pre-assembled with wireless charging coil already integrated.

Simply use this device with any QI Certified charger.

The RAPT Pill allows accurate and precise, true real-time specific gravity and temperature logging and control via wifi/bluetooth integration with the RAPT Fermentation Chamber or RAPT Temperature Controller, RAPT mobile app or RAPT IOT. 

The RAPT Pill acts as both a real-time gravity testing hydrometer and thermometer allowing instant gravity and temperature measurements and also logging from inside your fermenter during fermentation.

The RAPT Pill boasts many advantages over other wireless hydrometers and thermometers including tough design, better ergonomics, sanitary design and less susceptible to error as a result of hops, krausen or CO2 bubbles generated from fermentation.

IMPORTANT NOTE:
Ensure the RAPT Pill is charged for at least 24 hours before use. This is to ensure that it is fully charged and the battery is callibrated. You will not be able to access the Pill Captive Portal if the battery is insufficiently charged.

Once the RAPT Pill is connected via USB-C and connected to wifi, the firmware will automatically update to the current version (if needed). The Pill must be plugged in via USB-C and connected to WiFi in order to receive firmware updates. A 2.4gHz network is required.

DOWNLOAD THE APP

BLUETOOTH BRIDGE

Although the Pill Hydrometer will work in wifi mode the optimal solution is to use the Pill in bluetooth mode as this has several advantages including:
1. Bluetooth is more power efficient so it saves battery life.  This enables the Pill to save battery by only using power efficient as it's only giving out low energy Bluetooth beacons but then the bridge device that is connected to mains power is doing the heavy lifting and transferring that data to the RAPT web portal.  This is by far the most reliable way to use the Pill Hydrometer.
2. Bluetooth signal is better at penetrating through the fermenter more easily especially if you have a stainless steel fermenter or fermenter inside a fridge or fermentation chamber.
3. Bluetooth bridge mode allows you to use the Pill Hydrometer as the temperature probe to get a core fermenter temperature without the need for a thermowell.  The onboard Pill Temperature sensor is also very accurate as it's an onboard digital sensor with no flexible cable.  (please not if you have just charged or been in AP mode excessive heat from the battery does effect temperatures readings so wait 30min after charging for the battery temp to reach equilibrium)
4: Bluetooth connectivity allows for powerful fermentation control with the ability to use gravity and gravity acceleration to set automatic and accurate fermentation control.

To take advantage of the Bluetooth bridge mode you will need to pair the RAPT Pill to either a RAPT fermentation chamber (KL15813) or a RAPT Temperature Controller (KL22927).

Please watch the youtube video on how to do this.

LONG BATTERY LIFE
The RAPT Pill has a long battery life and can last 5 months between charges when utilising Wifi. If only using Bluetooth the battery can last 2+ years before needing to be recharged. The RAPT Pill has a USB-C charging port on the circuit board allowing fast charging from any USB-C cable.

How long will the pill last between charges?
60min telemetry frequency - 1.5 years
30min telemetry frequency - 9.5 months
15min telemetry frequency - 5 months
NOTE: This is the default telemetry frequency is 60 min so if you do not change the settings then out of the box the battery should last 1.5years approximately.

Pill Housing Design
The RAPT Pill housing boasts many advantages compared to other wireless hydrometers such as:

Made from strong BPA Free Nylon 12 and Polyketone(POK)
Both the clear Nylon 12 and Polyketone plast are food grade, FDA approved, BPA (and free of other types of bisphenol).  These are also plasticiser and phthalate-free.  They also contain no endocrine disruptors making them a much better choice than polycarbonate that is used in other products.  Nylon 12 and POK are also high temperature resistant, chemically resistant and extremly robust.
Greater ergonomics - The shape of the RAPT Pill has been designed for improved usability compared to other wireless hydrometers such that the Pill separates into two pieces at the midline of the Pill rather than requiring a difficult to remove end cap to be unscrewed.
Sanitary design - The RAPT Pill has no exposed thread and a double o-ring seal which allows for a water-tight seal with reduced risk of infection.
Less susceptible to error - The larger housing of the RAPT Pill compared to other wireless hydrometers means that the gravity logging is less susceptible to error from krausen, hops or CO2 bubbles from fermentation.
Different housing colours are sold separately on the website allowing customisation of your RAPT Pill. The colours available include:

RAPT Pill - Red Housing
RAPT Pill - Blue Housing
RAPT Pill - Green Housing
RAPT Pill - Yellow Housing
All units come with Yellow Housing pre-assembled
What is RAPT?
The RAPT IOT Hub is a free service whereby any RAPT enabled product can both log and store data to the hub where you can conveniently access this data.  The RAPT hub can also allow you to control your devices remotely giving you absolute control of the device irrespective of where you are.  The RAPT portal enables you to make complex temperature profiles that involve different temperature settings over time meaning you can start/run a temp profile giving you a set and forget experience.  The RAPT portal also controls the alert/notification process for you so you can receive email notification in the off instance that something doesn't go to plan.

There is no limit to the number of RAPT devices you can connect the RAPT IOT Hub. This is in contrast to other popular wireless hydrometers where you are limited by the number of hydrometers you can connect to an app.

Please note: The RAPT Pill is fully wifi and Bluetooth capable. Bluetooth integration requires a compatible RAPT Bluetooth enabled device such as a RAPT Fermentation Chamber or RAPT Temperature Controller

SPECIFICATIONS
*Accuracy: +/- 0.002 SG points
Temperature Range: -20C(-4F) and up to 60C(140F)
Pressure: 0-5bar
Battery: Li-Ion 18650 (we use the EVE Brand)
Size: 37mm Diameter x 125mm Long

Temperature Accuracy: +/- 0.2C (0.36F)
*Accuracy will be affected if solids are stuck to the outside of the pill hydrometer.  If you gently shake the fermenter from time to time this generally helps to wash hops and solid chunks of krausen off the body of the Pill and through the fermentation these will generally drop to the bottom of the fermenter.
